NEMA 3r Padmounted Secondary Bus Enclosures

Application

EPI NEMA Type 3r Padmounted Secondary Bus Enclosures are designed to allow distribution of large amounts of low voltage power. Ampacity ranges from the minimum of 600 to several thousand amperes at 600 volts and below, available in single or three phase.

Construction

Made from 12 gauge steel. A drip shield top and smooth seam. Free sides, front and back prevent falling rain, snow or sleet from entering the enclosure. Double doors with continuous hinge are operated by a three point latching mechanism with a handle equipped with padlocking provisions. Continuous hinge has a stainless steel pin. Flanged bottom opening for padmounting and conductor access. CD102 Copper is used and silver plated bus bars are sized according to one square inch of copper bus per 1000 amperes. Bus bars are insulated with 3" high 600 volt standoff insulators. Bars are punched with 9/16“ holes at 1¾“ each way to accommodate lugs.

Finish

The standard finish is ANSI-70 light dove gray inside and out.
